Canadian Passive House: Grey Residence

The Grey Passive House is located about 25 mins. from downtown Ottawa, on a well oriented, 90% unshaded lot in the Rideau Forest Estates. Casey Grey, of Cornelis Grey construction, is the owner/builder of Ottawa’s newest Certified Passive House. Stretched over three floors, including a walk-out basement/office, the building’s east-west axis is able to take full advantage of the high solar gains through the Thermotech windows.

Passive House challenges included the room above the garage, a 2-storey living room and entry, and the walk-out basement, which pushed the project towards higher thermal efficiencies.The deep 6’ wrap around porch not only extends the living space with the flare of a country residence, but also reduces the potential of overheating.
